Nwipe can now be configured from the kernel command line in grub.cfg using nwipe_options...., likewise the keyboard layout can be set from the kernel command line in grub.cfg using loadkeys=uk etc. A pause was added on nwipe exit so the summary table could be read. Pressing a key then starts a 5 second countdown to launch nwipe. Added the following additional software packages, memtest86, usbutils for usb-devices command etc, hwdata usb and pci, hidapi, libgudev, dosfstools, includes fatlabel, fsck.fat, mkfs.fat, e2fsprogs, includes fsck.
